IMPROVEMENT IN CORN-PLANTERS.

Specification forming-part of Letters Patent No. 40,492, dated November 3, 1863.

To all whom it may concern.-

Be it known that we, A. MERWIN and O. H. HOBART, of Padua, in the county of Mc- Lean and State of Illinois, have invented a new and Improved Corn-Planter; and we do hereby declre that the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, makinga part of this specification, in ,which Figure 1 is a side sectional view of our invention, taken in the line or m, Fig. 2; Fig. 2, a plan or top view of the same; Fig. 3, a section of a portion of the same, taken in the line 3 3 Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.-

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a rectangular'framc, which is formed of longitudinal bars a, connected at their ends by cross-bars b.

B is a drivers seat, which is secured to supports cin the frame A, and O is an axle, which is attached to the frame A at about its center. The wheels D D are at the inner sides of the outer bars, a, of the frame A, as shown in Fig. 2.

To the front part of the frame A there are attached a series of vertical bars, d, which are in a plane parallel with the axle 0. Two of these bars d are rather longer than the others, and to the lower ends of said bars there is pivoted, at a a, frame, D, to which two seed-hoppers, E E, are attached, and two furrow-shares, F F. The seed-hoppers have a slide, G, passing through them, which is perforated at its ends and serves as a seed-distributor, the slide being operated by means of a lever, H, which passes up through the frame A, just in front of a seat, I, on the frame A. This seed-distributing slide is arranged to operate in the usual way, and therefore does not require a particular description.

The frame D is connected by a toggle, J, to the under side of the draft-pole K of the machine, and this toggle J is connected at its joint by a rod, L, with a lever, M, the latter extending up through the back part of the frame A, by the side of the drivers seat B. By operating the lever M the frame I) may be raised and lowered through the medium of the toggle J. y The frame D is elevated in order to raise the furrow-shares F F above the surface of the ground-as,forinstance, in turning the machine at the ends of rows or in drawing it from place to place. The lever M may be secured in position by a spring-catch, N, which may be actuated so as to relieve said lever, when necessary, by the foot of the driver.

0 represents parallel bars, the front ends of which are secured by pivots e to the lower.

parts of the bars 61. These parallel bars form two frames, 0 O, of three bars each, the bars of each frame being connected at their back parts by cross-bars f f, through which and the bars Obolts g pass. Several holes may be made in the cross-bars f f for the bolts 9 to pass through, in order to admit of the bars 0 being adjusted nearer together or farther apart, as may be desired. (See Fig. ,2.) Each bar 0 has an inclined foot or standard, P, attached to it, and to these standards plows Q are socured.

To the back end of the central bar, 0, of each frame 0 there is attached a bar, R, and these bars B have levers S connected to their upper ends, said levers having their fulcra at h on the frame A. These levers S may be operated by the driver with his feet, so that set forth.
